NIRMAL.S Posted December 5, 2012 Report Posted December 5, 2012 How can we make a Eye Blink sensor...???Can we use other than IR for this sensor...?? Quote
Buffy Posted December 5, 2012 Report Posted December 5, 2012 You need to be quite a bit more specific about the conditions you need to run under. Does the sensor need to deal with picking out faces and then eyes? Or is its entire field of perception going to be limited to the eye itself? Do partial blinks count? Human-only or do we need to deal with sharks and geckos? Lighting conditions? Weather-proofing? Power limitations? What kind of sensor you use will probably depend on the answers to the above questions: it definitely does not HAVE to be an IR sensor, a visual-spectrum camera might be just as good or better, or maybe a laser or radar device. It's not foresight or hindsight we need. We need sight, plain and simple. We need to see what is right in front of us, :phones:Buffy Quote
NIRMAL.S Posted December 5, 2012 Author Report Posted December 5, 2012 i need sensors that don't affect our eye vision by any radiation .... Quote
blamski Posted December 5, 2012 Report Posted December 5, 2012 have a look at eye tracking software such as this one or this one any of these systems will be able to pick out that for a couple of milliseconds every so often the eye is not visible any more. this will be your blink detection. failing that, try coating the eyelashes in copper, wire the top set to 5V and the bottom set to ground and look out for the contacts.
